The most important and brightest full moon of 2023 will rise on Aug. 30, and its unusual title deserves a proof. Known as a “blue supermoon,” it’s the results of three lunar phenomena occurring directly. Such a uncommon cosmic overlap is not going to happen once more till 2037, in keeping with Stay Science’s sister website House.com.
The “blue” supermoon’s title has nothing to do with the moon‘s colour. In reality, it can really be orange. The blue supermoon will get the primary a part of its title for a distinct purpose: It is the second full moon in August.
There are two sorts of blue moon. The August blue supermoon falls into the primary class: two full moons occurring in the identical month. That is often inevitable; a brand new full moon rises each 29.5 days. Provided that the Sturgeon Moon occurred on Aug. 1, 2023, the Aug. 30 full moon might be a blue moon. Blue moons of this sort, referred to as “calendar blue moons,” happen roughly each two or three years, with the following one occurring on Might 31, 2026, in keeping with timeanddate.

The second sort of blue moon, referred to as a “seasonal blue moon,” describes the third full moon of 4 throughout one astronomical season. This happens when a calendar 12 months has 13 full moons as a substitute of the standard 12. (A lunar 12 months — 12 orbits of Earth by the moon — takes 354 days, whereas Earth’s photo voltaic 12 months is three hundred and sixty five days.) The subsequent seasonal blue moon, which additionally occurs each two or three years, will happen on Aug. 19, 2024, in keeping with timeanddate.
So, the place does the second a part of the title come from? A supermoon happens when the total moon is near its nearest level to Earth in its orbit. The moon’s orbit of Earth is elliptical, so each month, it reaches a closest level (perigee) and farthest level (apogee). Moons that come inside 90% of perigee in a given month qualify as supermoons, in keeping with Fred Espenak, an astronomer and former eclipse calculator for NASA.
August’s second full moon is the third and closest of 4 supermoons in 2023. At 222,043 miles (357,344 kilometers) from Earth, will probably be the largest and brightest supermoon of 2023, although will probably be solely 115 miles (186 kilometers) nearer than Aug. 1’s full moon, which was 222,158 miles (357,530 km) away.
The subsequent full moon would be the Harvest Moon, on Sept. 29. Along with being one of many best-known full moons of the 12 months, it is the final supermoon in 2023.
